About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-carat band, graded J colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2537921465. Listed at 8 retailers as of November 1, 2026, with prices from $3,754 to $5,847, a $2,094 spread on the same certified stone. Brilliant Earth lists it at $5,847. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
